dc.description.abstractAmong the remediation criteria applied to COPR in Hudson County, New Jersey are those based on the cancer risk associated with inhalation of Cr+6. For inhalation-based remediation criteria, the acceptable soil concentration is based on the concentration of Cr+6 on the respirable size particles. The default assumption is that the concentration of Cr+6 on those particles is the same as the concentration in the bulk COPR soil material. To examine this assumption COPR soil from 8 locations was separated into size fractions. The concentration of Cr+6, total Cr and Cr+3 was compared in the bulk soil and the individual size fractions including the respirable (<2.5 μm) material. Cr+6 was consistently enriched in the 2.5 μm fraction compared to the bulk COPR soil (mean enrichment = 63.7). In addition, the Cr+6 accounted for a larger percentage of the total Cr as the particle size decreased. In contrast total Cr and Cr+3 did not show a consistent enrichment in the 2.5 μm fraction. There was a strong relationship between Cr+6 concentration in the bulk material and in the 2.5 μm fraction that may allow analysis of Cr+6 in bulk COPR soil to be used as a surrogate analysis of the 2.5 μm fraction.en_US
